I saw the spot for this movie last night. They had all three disc format images on the screen with text indicating that it was out on Blu Ray Hi Def and DVD. The subtext noted a later release date for HD DVD.
On a side note, I had to laugh the other day when my wife insisted on buying the bathroom tissue with the "blue bear" on it while I wanted the "red bear" variety. You've probably seen the commercial of those two bears in a foot race to see who is better.
